Rattling gearbox when activating blades on Walker MS14

Hello Folks,

I picked up my Walker machine late in the summer of 2012. Over the last few weeks, I’ve noticed that engaging the blades through the PTO causes the gearbox to rattle insidiously. It also doesn’t seem to be capable of achieving the higher number of engine revs – I must mention that this happened after allowing leaves to build up in the exhaust. Is anyone aware of a fix?

Hi Euan,

It’s important that you clean out your mower’s deck, exhaust and underside after every mowing session to prevent this buildup. I think your mower could be running on one cylinder – use the plug wires to determine if both cylinders are working. If this isn’t the issue, I suggest inspecting your carburetor and the fuel system. Ensure that your drivebelt is also secured properly and not running loose as this could also cause the rattling. If you’re unable to resolve this issue yourself and the vibration becomes excessive, it would be advisable to take the unit to an authorized technician.

Walker MB19 electric starter and engine trouble

Hi Guys,

I purchased by Walker non-collecting mower back in 2014 and had no issues with it until the last month – the electric starter motor tends to stick and requires removal often, almost every 20 hours for cleaning. Is there any quick fix to this problem? It’s a Kohler 20 hp engine.

Hello Jim,

I experienced the same problem on my mower for a year – I’d sometimes have to turn the key several times to get it to start. I did notice that cleaning out all the connections, especially the ones near the battery, can drastically improve starting. Aim to keep all the cables tight as well. If none of these help, try replacing the lubricant.

PTO switch does not engage the cutting blades

Hey everybody,

I’ve owned my Walker MB19 for a little over a year, and I noticed today that the PTO switch does not engage the cutting blades anymore. The blades are brand new and the entire assembly has been lubricated last week. Does anyone know what I could do to fix this?

Matt

Hello Matt,

It’s possible that your blade clutch may have worn out. Remember that your clutch will undergo normal wear-and-tear with use and needs to be replaced when required. You can prolong clutch life by maintaining low engine speeds while engaging or disengaging the blade clutch. If replacing the clutch doesn’t solve the problem, have the wiring inspected by an authorized professional.

Engine stalls without warning

Hello Guys,

My Walker mower’s engine tends to die all of a sudden, right in the middle of a mowing session. I’ve check the fuel levels, oil levels, drive belts, clutch and all other components but everything seems to be fine. Does anyone know what could be going on?

Rebecca

Hi Rebecca,

Have you checked your fuel cap? Fuel caps usually have a tiny opening that allows air to enter the chamber as gasoline is being consumed by your engine. This offsets the pressure difference and allows fuel to keep flowing. Over time, it’s likely that your fuel cap’s gap was sealed by debris and dirt. This block creates a vacuum as fuel is drawn out of the chamber, preventing the engine from consuming any more fuel. Try cleaning out your fuel cap, or replacing it with a new one.

MT25i Walker mower struggling to cut evenly

Hi Folks,

My walker mower has lately been struggling to plough through my lawn, even though the blades are fine – I replaced them two weeks ago. When it does cut, the trim is far from even. There are no issues with the engine or any other components as far as I can see. Any ideas what’s causing the loss in cutting power?

Phillip

Hey Phillip,

Cutting issues are commonly caused by not mowing with right parameters adjusted and weather conditions. Since you mentioned that your mower’s engine and other parts have no issues, do you generally mow in wet conditions? Mowing wet grass can be difficult for your blades to catch properly and it’s recommended that you wait until the lawn is dry. If you must mow in wet conditions, mow each section twice – first with a higher height setting and then with the desired setting. Cutting tall grass can also make it difficult for you to get an even cut the first time. Follow the two-step mowing approach and hopefully it should resolve your issue.

Walker mower using excessive fuel

Hey there,

My walker MB23i is over six months old and the fuel consumption seems to have shot up drastically, especially within the last month. It runs really well and I’ve had no issues with power or reliability, but the fuel mileage seems to be almost half of what my neighbors are seeing on their mowers. Is there any reason for this?

Hamilton

Hello Hamilton,

There could be a number of reasons for excessive fuel consumption – do you clean out your mower’s blades, underside and deck after each mowing session? Failing to do so can put your engine under additional load and force it to consume more fuel – this won’t be easy to notice when mowing, especially considering your mower is just 6 months old. Also ensure that you clean your air filter elements after every 25 hours of use because a dirty air filter also wreaks havoc on fuel efficiency. Finally, check your carburetor settings and ensure that your air-fuel mixture is appropriate to the conditions you’re mowing in. Cold weather calls for a higher fuel mixture while lower mixtures will work fine in warmer temperatures.
